9.8 Reverse action of the control function (actual Value>Set = n+)
For the effect of the regulation there are TWO functions
1. Setting ON for actual Value>Set = n+ = increasing output voltage at increasing actual value
2. Setting OFF for actual Value>Set = n+= decreasing output voltage at increasing actual value
Example for Temperature control:
Heating function e. g. for heat exchanger Cooling function e. g. for building climatisation
For special applications an external switch over of control function is possible (FIO Setup → Reverse fo control
function).
